Description
Plotly (Dash) not updating xaxes range via Patch method when 2 subplots are horizontal make_subplots(rows=1, cols=2, shared_xaxes="all"). It works fine when the two subplots are vertical.
Plotly / Dash versions
plotly 6.5.2
dash 3.4.0
Screenshots/Video
Horizontal: On 1st Forward or Backward click half the trend disappears, because the range does not get updated.
Horizontal: On 2nd Forward or Backward click half the trend disappears, because the range does not get updated.
Vertical Subplots are OK! You can hit Forward/Backward as many times as you want
Steps to reproduce
- Run attached code
- When Dropdown is Horizontal (default), use Forward/Backward button and trend will disappear in two clicks. The x-range does not keep up when the trend is updated via the Patch method
patched_figure["layout"][f"xaxis{index + 1}"]["range"] = [now, now + timedelta(days=4)] - When Dropdown is Vertical, all works as is should. You can hit Forward/Backward as many times as you want.
